ECO Farm 4'' Ventilation Kit VS Spider Farmer Fan & Filter Bundle 4 Inch

Ventilation is a vital factor in your plant growth. By supplying fresh air from outside your grow tent, you provide CO2 for your plants, driving their photosynthesis. At the same time expelling the air inside will keep temperature and moisture build-up under control, preventing mold and mildew from forming on your plants’ leaves, inhibiting growth. Refreshing the air inside has the added benefit of removing strong odors. The following guide will show you what you need to know about setting up your ventilation system.

What Size Inline Fan do I Need?

There are various sizes of grow spaces, each requiring a different amount of airflow to ventilate them. Exchanging stale air inside with fresh air from the outside of your grow space is vital for optimal plant growth. This figure is measured in CFM or cubic feet per minute.

To find the amount of airflow needed for your grow space, first find its volume in cubic feet. Most grow tents’ measurements are given to you in inches, so convert your space’s dimensions from inches to feet. Then multiply its length by its width and height. This will equal your grow space’s volume, with the required airflow equal to this figure in cubic feet per minute, or CFM.

For example, a 48”x36”x72” grow tent converted to feet would be a 4’x3’x6’ grow tent. Multiplying the dimensions together would equal 72 ft3. Since a grow space’s volume is also the required CFM to ventilate it every minute, this grow tent’s base CFM is 72.

Below is a comparison of two ventilation kits, I hope it can be helpful to you.

Why Do You Need to Ventilate Your Grow Room?

So why do grow rooms and grow tents need to be ventilated? As it turns out, there are quite a few reasons.

Plants grown outdoors enjoy the mitigating effects of light breezes, sunshine, evaporation, and precipitation. Indoors, we substitute fans for breezes and evaporation, grow lights for sunshine, and watering systems for precipitation. What we often forget about is that outdoors, air circulates more naturally than in your grow room.

You need both a fan and an air filter to keep the air in your grow room fresh. Here’s why.

Remove Excess Heat
Grow lights emit heat. It might not seem like much to you, but a few degrees in temperature can mean the difference between a successful crop and a less successful one. Certain grow lights emit more heat than others, but all produce enough heat to merit ventilation.

Control Humidity
Humidity is another factor that can contribute to problems with indoor growing systems. Plants emit water vapor throughout the day which increases the humidity of your grow room. Uncontrolled humidity leads to poor growing conditions and can result in the development of pests and diseases.

A good ventilation system also wicks away some of the water released during transpiration, allowing your plants to absorb more water and pull up nutrients through their root systems, boosting growth.

Prevent Pests and Diseases
Air circulation helps prevents pests and diseases. Mold, powdery mildew, spider mites and fungus gnats prefer stagnant, humid conditions. Pests lay their eggs in damp topsoil, so having a fan to keep the surface layer of soil dry can slow their reproductive cycle, and a steady breeze makes it harder for them to establish themselves on your plants in the first place.

Control CO2
Plants need outside air for one very basic reason: CO2. Plants absorb CO2 throughout the day as part of their nutrient cycle. If your grow tent setup is sealed, this means that the level of CO2 in the room gradually decreases, limiting your plants’ growth. Ventilation brings in fresh air and fresh CO2 from outside and removes the old air from your grow room, boosting growth and yields.

Manage Wind Stress
Outdoor plants are constantly buffeted by the wind. This makes the stems of the plants stronger, which serves them well when the time comes to bear fruit. Stronger plants produce and grow better than weaker plants, which can break under the weight of their own yields.

So why do you need a grow room ventilation system? Let’s review. A good ventilation system:

Reduces the chances of diseases like mold and powdery mildew from developing
Helps protect your plants from pests like spider mites and fungus gnats
Helps you control the temperature and humidity of your grow room
Helps strengthen the stems of your plants.

Inline Fans Buyer’s Guide

Before you get your new fan, there are some things you should know, and certain features they possess which make them better. Without further ado:

The Size Of The Grow Area

Before anything else, you need to determine what size your area is. This is important because different sized fans will have different rates of air circulation, and you want optimal circulation in your room for the best results. Luckily, there is an easy formula to determine the ideal size for your room. All you have to do is multiply the height of the room by its width, length, and 1.25. It helps give you an idea how much air should be removed from the room.

The Heat Of The Lights
Since some lights generate more heat than other, you’ll need to determine what kinds you’re using and then see which type of fan corresponds to that. HID lights tend to heat up the place more quickly, so in that case, you’ll need a fan that can handle and remove the heat, for example.

Diameter Of The Fan
As you may have noticed, fans come in various sizes. It’s not always easy to choose the diameter you need. After all, there are those of 4” up to those of 16”. If you want a safe bet, get a 6” diameter fan. That’s because the most common indoor set up will be to accommodate that size perfectly. If that happens not to work for you, you can simply get a converter instead of an entirely new fan.

Conclusion

As you may already know, there are a few things that are essential for successful marijuana growth, and one of those is definitely inline fans. They keep things fresh and the air moving, which we all know is essential for quality photosynthesis. Because let’s face it, no matter how much better marijuana is from other plants, it’s still a plant.

Remember that if you take good care of your plants, they will take good care of you, too. It’s also much better that you’re growing your own stuff because you never know where the one you buy comes from or what might be in it. This is a much safer alternative, and it can prove to be cheaper, too.
